The new Datum 10 features a 24/30-ton high-modulus carbon fibre frame which has a compact geometry with mudguard eyelets and generous clearances. Most bikes tend to use the rear wheel cutout for aero gains, instead Genesis have used it to enable clearance for up to 33c plus 45mm mudguards without having to resort to an overly long chainstay. Genesis have paired the frame with a full carbon fork which features discreet mudguard eyelets and Shimano flat mount interface. The Datum 20 is equipped with Shimano's 105 11-speed drivetrain with wide range 50/34T x 11-32T gearing. Braking comes from Shimano's new RS505 dedicated hydraulic brakes with 11-speed mechanical shift which produce assured and powerful braking in all weather conditions. To keep you rolling Genesis have used Fulcrum Racing Sport DB wheels that have a new-school wide 23/17mm rim profile and a lightweight of only 1872g. The wheels are wrapped in brand new 700x33c Challenge Strada Bianca tyres which feature the same proven tread found on the Paris Roubaix, a new, even larger volume 33c casing, puncture protection strip and low weight of only 355g. Completing this great build is Genesis own brand kit including handlebar, stem, seatpost and saddle.

The Datum Range

After the successful launch of the Zero range Genesis have now designed the Datum series which is their second carbon-framed model. Using the same geometry as the longstanding Equilibrium as a starting point, the new Datum is a large-tyred road disc bike that’ll comfortably sit mile-after-mile on tarmac, but, should the tarmac come to an end, won’t mean turning back or the premature end of the ride. Not necessarily about out-and-out overall speed, but more fun, adventure, exploration and pneumatically-suspended comfort. With it's lightweight frameset, great choice of components and larger 33c tyres the Datum range is ideal for riding around and enjoying yourself, across a variety of terrain, both paved and unpaved, albeit fast or somewhat more leisurely. No matter what your riding adventure the new Datum range will step up and deliver no matter what type of terrain you are pedaling it along.

Genesis bikes are designed and developed by a small group of riders to fulfil the demands of those who make the UK riding scene one of the most diverse and exciting in the world. With an advantage derived from focusing purely on the UK market allowing Genesis to offer a wide range of complete bikes and framesets that have tangible benefits on home ground.
A bike that's been honed on the steep roads, precipitous mountains or hectic streets of the UK has earned the confidence to take on anything it may come across, anywhere in the world.

Genesis offer bikes that defy categorisation and offer something different, each model is devised to suit a particular riding style or feel. First through prototyping, then frame development and finally production, with lots of riding opportunities throughout the process! This extensive testing makes all their bikes more than the sum of it's parts, one that encourages you to ride that bit more.
